Question : If $\theta$ is a positive acute angle and $\tan2\theta \tan3\theta=1$, then the value of $2(\cos^2\frac{5\theta}{2}-1)$ is:
Option 1: $-\frac{1}{2}$
Option 2: -1
Option 3: 0
Option 4: $\frac{1}{2}$
Correct Answer: 0
Solution : Given: $\tan2\theta \tan3\theta=1$ or, $\tan2\theta=\cot3\theta$ or, $\tan2\theta=\tan(90-3\theta)$ or, $2\theta=90-3\theta$ or, $5\theta =90$ $\therefore \theta=18°$ $2(\cos^2\frac{5\theta}{2}-1)$ = $2(\cos^2\frac{5×18°}{2}-1)$ = $2(\cos^245°-1)$ = $2×((\frac{1}{\sqrt{2}})^2-1)$ = $2×-\frac{1}{2}$ = $-1$ Hence, the answer is -1.

Question : The radius of the base of a hollow cone is 8 cm, and its height is 15 cm. A sphere of the largest radius is put inside the cone. What is the ratio of the radius of the base of a cone to the radius of a sphere?
Option 1: 5 : 3
Option 2: 4 : 1
Option 3: 2 : 1
Option 4: 7 : 3
Correct Answer: 5 : 3
Solution : Given: The radius of the base of a hollow cone = 8 cm Height = 15 cm Now consider the problem in two dimensions. Area of the triangle = $\frac{1}{2}\times$ base $\times$ height. The inradius of the circle = $\frac{A}{s}$, where $A$ is
